There is a "reject" on my system using the "as" command, but I assume that's normal when authentication is disabled. Comparing your "frequency" and "stablility" with the values on my server leaves to wondering if something isn't working correctly. It seems like I should have numbers here, but I'm still reading the documentation. ntpq> pe remote refid st t when poll reach delay offset jitter ======================================================================== ====== tock.usno.navy. 0.0.0.0 16 u - 64 0 0.000 0.000 4000.00 ntpq> as ind assID status conf reach auth condition last_event cnt =========================================================== 1 51964 8000 yes yes none reject ntpq> rv status=c011 sync_alarm, sync_unspec, 1 event, event_restart, version="ntpd 4.1.1c-rc1@1.836 Thu Feb 13 12:17:19 EST 2003 (1)", processor="i686", system="Linux2.6.4-thinUSB-ch1", leap=11, stratum=16, precision=-17, rootdelay=0.000, rootdispersion=0.360, peer=0, refid=0.0.0.0, reftime=00000000.00000000 Thu, Feb 7 2036 1:28:16.000, poll=4, clock=c409f3ef.98226809 Mon, Mar 22 2004 18:23:27.594, state=1, offset=0.000, frequency=0.000, jitter=0.008, stability=0.000 ntpq> Thanks, Mike Chirico ___________________________________________________________________________ Philadelphia Linux Users Group -- http://www.phillylinux.org Announcements - http://lists.phillylinux.org/mailman/listinfo/plug-announce General Discussion -- http://lists.phillylinux.org/mailman/listinfo/plug
